A 13C{1H}-NMR spectrum is defined as a type of spectroscopy technique used in chemistry to analyze the carbon and hydrogen atoms in a compound by measuring the chemical shifts of the nuclei in a magnetic field. AI generated definition based on: Journal of Organometallic Chemistry, 2011 ...
. The simulated IR spectra of CO adsorptions on the surfaces of Cu and Cu2O are in good agreement with the experimental SEIRA spectra. Noticeably, the vibrational intensity of adsorbed CO bands on the Cu2O catalysts using GNSs is significantly enhanced compared to that using CDFs as the substrat...
Si(O)OSi is active in the microwave region of the electromagnetic spectrum and could be observed via radio telescopes. Table 2 provides additional Si(O)OSi theoretical spectroscopic and rotational constants. However, silicon is less abundant than carbon. Furthermore, Si(O)OSi has smaller predicted...

The X-ray photoelectron spectroscopy (XPS), temperature-programmed desorption (TPD) and infrared spectrum (IR) results suggest that besides the oxygen species of BSCF and LSCF, the OH-related species can be detected on BCFZY, which can play a promoting role in oxygen catalysis activity. The ...
